FURNACE FOR CURINGTOBACCO.

SPECIFICATION forming part of Letters Patent No. 301,864, dated July 15, 1884. v

To all whom it may concern Be it known that I, WILLIAM F. OoUL'rER, a citizen of the United States, residing at Olarksville, in the county of Montgomery and State of this specification.

This invention relates to devices for the curing of tobacco; and its objects are, first, to provide a simple and portable apparatus for the curing of tobacco by heat or smoke; secondly, to enable the curing to be effected by box-furnace, with suitable arrangements for draft and for the escape of smoke either into or outside of the drying-house.

This furnace, when in use, is to be erected upon the earthen or brick floor of an ordinar tobacco-barn or drying-house. I

In the accompanying drawings, Figure l is a perspective of the furnace erected, taken from the direction of one of the front corners; Fig. 2, an interior perspective of one of the side walls of the furnace,with the slide partly closed; Fig. 3, an exterior perspective of they rear wall of the furnace, and Fig. 4 an interior perspective of the top of the furnace.

Like letters refer to like parts throughout the series of drawings.

A A are furnace side walls, consisting each of a frame of bar-iron filled in with sheet-iron. A wire-cloth panel, a, occupies the full length and about one-fourth of the width of the wall, to permit the escape of smoke into the dryinghouse to assist in the curing of such kinds of tobacco (as those of Tennessee and Lower Kentucky) as need the aid of smoke in curing;

but when heat alone-is needed (as in the case of tobacco of Upper Kentucky, Ohio, Missouri,

In that case the smoke is carried outside the drying-house by means of 'an ordinary pipe fitting upon the collar B,from Which the cap I) is removed, said cap being f closely fitted upon the said collar whensoever u the wall directly, but in alarge swinging door,

Vertical slots a are cut downwardly in the top and bottom frame-bars of the walls AA, and similar slots, d, are cut upwardly in the and D, and these slots, fitting one into another, enable the four walls to be dovetailed together, so as to form a level rim about the furnace, on which the oval top E may closely rest. The oval top or cover E consists of sheet metal, with flaps e e to close against the upper edges of the side walls of the furnace. At either end is a bow-shaped rib, e, with a stringer, '6, attached at the outer side of the bow. The sheet-metal top is riveted to the upper surface of the bow, and a fan-piece of sheet metal, 6', is riveted to the sides of the bow and stringer, thus closing in the end of the cover. The stringer of the center rib, f, is bent downward at both ends, so that the stringer may fit against the interior surfaces of the upper edges of the side walls of the furnace to aid in keeping the top or cover in place when fitted. Handles g g' are attached to the cover, whereby to lift it conveniently.

The fire is kindled upon the dirt floor of the drying-house, or'in a grate or pan set inside the furnace.

When not in use, the furnace may betaken apart and stowed away in a knockdown con- 5 A furnace for curing tobacco, consisting in the combination of the walls A, having, the
